. rack attached to the lower side of the seat.

The object of my invention is to simplify and cheapenthe construction ofthe chair shown in the Said patent and make it more durable. In

this my present invention I have divided each leg into two parts, havepivoted one part of each leg upon a depending rigidpart of theseat-frame, and above the said pivots I have placedtwo pinionsprovidedwith straps having at their sides studs, one of which is caught atsuitable times in one ofa series ofthree notches of a locking device(shown as acatch) pivoted upon the other strap. The outer ends of thesestraps are connected with the movable side pieces of the pivoted legs.

The particular features constituting myinvention will be stated in theclaims at the end of this specification. v

Figure 1, in full lines, represents in side elevation one of my improvedchairs in its most elevated position, the dottedlines showingthe seatlowered and the legs turned to form a rocking-chair. Fig. 2, in fulllines, is a side elevation of my improved chair in its second positionas a high carriage, the seat beinglower than in Fig.1, while the dottedlines Show the said seal: lowered to its third position to make a lowercarriage. Fig. 3 is adetailof the looking device detached, and Fig. 4.is a Section of the strap on the dotted line as a: to show the studengaged by the said locking device.

The seat a, arms a, back a and rigid part oted, are all as usual. Eachleg is composed of'a part, i), suitably curved to serve as a rocker, anda part, b, hinged or pivoted upon: it at b The upper end of part b ispivoted at c to the rigid part j of the seat-frame.
